In LPL, Not able to use Derived user fields on Action forms and Rules as it is erroring out as "Invalid Field". Please help if there is any other way to fix it.
Can you provide some more context of how you are trying to use a derived field on an action form? Derived fields can't be updated explicitly, given that they are derived. Are you just trying to display the derived value on the action form?
Did you figure this out? We are having an issue with this as well.
